A dual 3-port boost control solenoid kit for GT-Rs running an AMS Alpha turbo kit with standalone engine management such as MoTeC or Syvecs. One solenoid controls the top wastegate ports and the other controls the bottom ports, giving much finer boost control resolution than the factory solenoid.

Includes: dual 3-port MAC valves, vacuum line, fittings, wiring and mounting hardware.

Fitment: 2009+ Nissan R35 GT-R (USDM, JDM and European models, LHD and RHD). Will not work with the stock ECU (Cobb/EcuTek).

Not legal for sale or use on emissions-controlled vehicles in California.
